When trying to turn my tv on the unit chimes then there is a click then the chime then a click & this cycle repeats 10 or 12 times until the tv finally powers up. Is this a power supply problem?

To The Knight: followed your advice, nothing came up for my samsung LN52A650A1FXZA. will keep searching the problem.
Horizontal line problem is usually related with T'Con board itself. In rare cases, with panel too. There is details about this, at one or tow among the posts with the blog I've pointed out to you. I do clearly recall that, I've seen it there. It is a site, has more than 400 indexed pages on Google. a helpful one too. I've pointed out to many others, and most of them did find solutions to their problem there. I do get their responses too; by Fixya.
Just understand, an LCD TV is working mearly by some capacitors, and some users trusted as it is.
Contact any service technician. It will be the best.

Tv real slow about powering up
Happened to me. I called Samsung and they sent a serviceman out. I can't remember what the problem part was called but it was a problem they evidently knew about and fixed it for free...the first time. It hasn't done it again (knock on wood)...so you should call them if it's a Samsung TV.

Why is my startup screen red and picture color rainbowish?
Hi
Thanks for
using FixYa. From what you have described it seems that you might have a backlight and/or an inverter
board issue with this TV set. It could also be due to the inverter
circuits for the backlights. The inverter is the power supply source
for the backlights. There could also be a screen driver problem; if it is
then you have to change the entire inverter board. All this is only recommended
if you have some kind of expertise for checking the internal circuitry of the
TV as these units have high voltages running even when the set is switched off.
The cost to change the inverter board including labor would be around $250, if
you get this done by a professional. Please revert back for more help.
